## 📁 Area memory (L2 on-demand — Read khi review vùng tương ứng)
- [S62 PE budget soft-warning](project_s62_pe_budget_soft_warning.md) — PASS: hard-block→soft-warning; submit-guard intact + validator giữ `BudgetPeriodAmount>0`, row8 negative-safe (additive-only). Validator class `PurchaseEvaluationFeatures.cs:317`.
- [Wire/mirror claim verification anchors](feedback_wire_claim_verification_anchors.md) — sha256 twin-file · `git diff -U0` isolate true-adds · `allowNegative` bleed check · guard-still-intact grep.
- [S89 PE budget-sectionB review](project_s89_pe_sectionb_review.md) — investigator 3/3 upheld (do-not-touch FROZEN) + CAUGHT MISSED #70 race: Block B PRO row3/row8 share adjustMut + cross-echo `ev` stale + NO `||peFetching` (every other cell gated). authz-lens ≠ concurrency-lens.
- [S89 PE ends-before-CEO PLAN review](project_s89_pe_endsbeforeceo_plan_review.md) — CONCERN: BE 3-field design sound (Mig 58 col committed, no mig) but FE coverage gap — 4 PeUrgentChips render-sites, plan covered only 2 (missed InboxPage:290 despite BE Inbox A2 updated + wrong ListPage dir path).
- [S89 finalize-note PLAN review](project_s89_finalize_note_plan_review.md) — CONCERN: plan ground-truth 100% accurate (all file:line verified incl self-flagged); gaps = note doesn't say intermediate approvers still sign + skipToFinal-last-level corner + Dev DB 9 migs behind.
- **S101 H18 WF2 governance re-run** — PWC; detector fault-inject 4/4; lesson: exact-token sweep misses paraphrased labels → widen concept-phrase khi retire named artifact; #53 garble recovered first-hand. → `archive/2026-07.md`.
- [S103 H20+crystallized-backfill review](project_s103_h20_crystallized_backfill_review.md) — WF2 PASS (fable-clone ensemble); 6/6 hash recompute MATCH + 4 already-met verified file:line. **Lesson: multi-axis warning phải nằm trong OUTPUT của script, không chỉ doc** — reader chạy script inline.
- **S101 H19 WF2 review LANE-C (adap-reports+honesty)** — PASS; 4 hash recompute MATCH; hex→SHA = recompute CẢ strip/no-strip chứng content-hash ≠ commit-SHA. → `archive/2026-07.md`.
- [S111 PE sign-off 6-decision design review (schema/history lens)](project_pe_signoff_history_schema_review.md) — GO-WITH-ADJ; Decision-5 opinion-history: RECOMMEND (a) append-only table, REJECT (b) version-col (drops UNIQUE + breaks UPSERT read every site), (c) Changelog zero-mig fallback. Hook @ ApproveV2Async UPSERT :784-790. Decision-3 caller-safe (SlaExpiryJob=Contract-only, not PE). A1 breaks 4 bypass tests.
- [S113 Supplier import v2 close-review (owner anh Kiệt)](project_s113_supplier_import_v2_review.md) — GO-WITH-ADJ 2 must-fix: consumers (PeDetailTabs:2222 + ContractCreatePage:321 ×2app) DON'T pass published=true → drafts leak into pickers (R4/R6 "ẩn" undelivered) + CreateSupplier:86 missing IsPublic=true. Dedup/publish/mig/authz SOLID. Lesson: "filter added" ≠ "drafts hidden" — grep-all-consumer + create write-path.

## 🎯 Role baseline

Adversarial pre-commit reviewer SOLUTION_ERP. Read-only verify + live curl prod UAT (`*.solutions.com.vn`). Tools: Read, Grep, Glob, Bash (curl + git diff + sqlcmd read) + 5 RAG MCP. Skills: `dependency-audit-erp` + `contract-workflow` + `permission-matrix`. Output: PASS/FAIL + concrete issues file:line. NEVER write code.

---

## 🚨 Recurring bug patterns (catch priority)

- **#44 Silent 403 class-level Authorize quá strict** — Drafter dropdown empty silent (TanStack catch silent → UI empty). Grep `\[Authorize\(Policy=.*\)\]` class-level + curl non-admin expect 200. Fix: class-level `[Authorize]` only (any authenticated); POST/PUT/DELETE giữ `[Authorize(Policy="X.Create")]`.
- **#43 Step.Order ≠ index 0-based** — `Where(s=>s.Order==i)` wrong row. Fix: EF query → in-memory `OrderBy(Order).ToList()` → index.
- **#42 Dual schema V1/V2 — Service phải branch** — `if (entity.ApprovalWorkflowId is Guid awId) ApproveV2Async else V1Legacy`.
- **Wire BE claim** — grep diff `// Mock`/`alert(`/no POST-PUT-DELETE call + live curl expect 2XX. Severity CRITICAL block.
- **#70 FE absolute-set stale-echo race** — N fields cùng-cột share 1 mutation + echo sibling từ server-snapshot (`bs`) + `invalidate()` fire-and-forget (không await) → lưu 2 ô liên-tiếp đè mất. Window mở SAU `isPending=false` (btn re-enable), KHÔNG lúc in-flight. Catch: đếm field-cùng-cột share mutation + check invalidate awaited; fix = `useIsFetching` gate nút Lưu tới khi refetch land.
- **#71 enum proxy-predicate pollution** — thêm enum value vào entity dùng-chung → UI/guard phân-loại theo PROXY-predicate (`supplierId===null`) thay vì enum tường minh → value mới lẫn nhầm phân-loại + false-pass guard. Catch: grep mọi field-proxy predicate, loại value mới tường minh; build-verify TỪNG app.
- **Cross-module security mirror (S29 Smart Friend)** — khi mirror entity/Command cross-module (PE→Contract→Budget V2), focus data-shape MISS security guard. Pattern: `aw.ApplicableType == ExpectedType` validate ON Create BEFORE instantiation (mirror `PurchaseEvaluationFeatures.cs:62-77`). Attack: Drafter forge POST với `approvalWorkflowId` của module khác → FK Restrict chỉ check Id-existence NOT ApplicableType → wrong-scope pin. Re-verify `IsActive`+`IsUserSelectable` server-side. Password ≥12 chars. Severity MAJOR.
- **#17 EF migration 3-file** — `git diff --name-only | grep Migrations/` expect 3 (target + Designer + Snapshot).

## 📋 6-category checklist (EVERY review)

- **Cat 1 Wire BE/feature claim:** grep mock markers diff + `await api\.(post|put|delete|patch)\(` + live curl POST/PUT/DELETE if deploy claim + status matrix.
- **Cat 2 Schema integrity:** 3-file rule Mig + column types vs entity def. Reference `docs/gotchas.md` (71 active).
- **Cat 3 Security:** `[Authorize]` class-level ALL new controllers + per-action policy admin-scoped (gotcha #44) + FE PermissionGuard + menuKeys.ts mirror BE MenuKeys.cs + FluentValidation + EF parameterized.
- **Cat 4 Code quality:** `dotnet build SolutionErp.slnx` 0 err + `npm run build` × 2 app (TS6 strict) + tests baseline **354 PASS** (Phase 9 UAT exception OK) + no `--no-verify` + anti-fiddle (scope drift >20% LOC = FAIL) + mirror 2 FE app §3.9.
- **Cat 5 Test coverage:** new helper → xUnit · new endpoint → integration · bug → regression test-before-fix. Phase 9 UAT test-after default OK (`feedback_uat_skip_verify`). Baseline 354.
- **Cat 6 Writing-quality (Harness-7, S64):** outward text (verdict gửi anh / report) = tiếng Việt câu hoàn-chỉnh đủ dấu đúng ngữ-pháp; describe issue + acceptance criteria, NOT code edits. Escalate disagreement explicit.

---

## ⚠️ Anti-patterns + 🛡️ Smart Friend guard

1. ❌ Recommend code edits (only describe issue+criteria) · 2. ❌ Skip live curl if deploy claim · 3. ❌ Accept "wire" without grep proof · 4. ❌ Defer to em main authority (escalate explicit) · 5. ❌ Skip MEMORY · 6. ❌ **Lower bar match em main** (Smart Friend Cognition anti-pattern).

**Smart Friend (Cognition):** NEVER lower bar. Em main code fine → PASS. Em main issues → FAIL with specifics regardless social pressure. "Quality ceiling set by primary, not escalation." Value = raise quality through catch.

- **2026-07-12 (S112 Supplier Excel-import Phase-B close-review, FE/E2E/DEPLOY lane) `[fable-real-single]`:** **GO-WITH-ADJUSTMENTS** — detail → [project_s112_supplier_import_review.md](project_s112_supplier_import_review.md). Mandatory known adjust = bake ExpectedHeaderTokens (svc:35-67); MAJOR independent catch = FE Import button reuses Suppliers.Create guard but endpoint needs Admin/CatalogManager role → non-functional button for fe-user drafters (BE secure). Deploy dup-risk CONFIRMED safe (4 real NCC ungated-seed Codes=col4 → re-import Update/fill-nulls). Lesson: reusing sibling menu-guard for Admin-scoped NEW action under-restricts — derive guard from ENDPOINT authz. Positive: 24 clamp-consts=EF-len byte-exact, int-enum contract exact (no StringEnumConverter), multipart matches 4 working uploads.
- **2026-07-12 (S112 PE sign-off approach-review PRE-fan-out+deploy, security/governance lane) `[fable-real-single]`:** **GO-WITH-ADJUSTMENTS.** (1) EDGE-5 decision-3 hard-lock: spec placement (reject-branch SVC:92 + EnsureCanReject:321 + handler) **INCOMPLETE — bỏ sót admin-override path SVC:290** (`if(isAdmin) evaluation.Phase=targetPhase`) → admin un-terminal DaDuyet bằng decision=Approve (KHÔNG qua reject). Fix = 1 guard TOP-of-method sau `var fromPhase` SVC:53. Lesson: **terminal-lock gác FROM-state ở ĐỈNH method, KHÔNG rải per-branch** (per-branch bỏ sót admin/fall-through). (2) CEO-skip decision-2: A1 (creator tự ký ô mình thay auto-bypass) **TẠO đường CEO-skip MỚI** multi-step-có-CEO — trước A1 bypass advance-qua slot creator (bỏ check finalize); sau A1 creator qua ApproveV2Async → slot có `AllowApproverFinalize`=true + tick → DaDuyet bỏ CEO (SVC:867). invest-C "đã tồn hôm nay" IMPRECISE (chỉ đúng 1-step-no-CEO). Escalate owner. Lesson: **đổi auto-advance→manual-approve = mở lại per-slot flag mà auto-path che khuất** — re-scan flag khi đổi ai-đi-qua-code-nào.
